A large number of topics have come up that wish to make Python more "fluent" (https://en.wikipedia.org/wiki/Fluent_interface).  This is an example of the same general idea.  In every single case, the goal has been almost universally rejected as opposite Python's attitude.

Converting fun(a) to a.fun() might be possible automatically, but if most such fun() functions return None because they are mutating functions, this does not get chaining of methods, which is the underlying goal.  While technically, Python *could* usually return self from most method calls (and libraries like Pandas do exactly that), the Python developers have very deliberately decided that they don't want that.

Is possible some day add Uniform Function Call Syntax (UFCS) in Python like Dlang?

The dead increasingly dominate and strangle both the living and the
not-yet born.  Vampiric capital and undead corporate persons abuse
the lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
